Description

Technical Field

[0001] The utility model relates to the technical field of wiring terminals, and more specifically to a new direct terminal seat for a three-phase intelligent electric energy meter of a national grid. Background Art

[0002] Terminal blocks, also known as terminal blocks, terminal strips, terminal boards, terminal blocks, terminal strips, terminal blocks, etc., are an important connection component in the field of electrical engineering. Their main function is to provide a reliable interface for fixing and connecting wires, cables or other conductive parts to achieve electrical connections between circuits. Terminal blocks used to install wires are usually installed in machinery or electrical equipment, and electrical equipment is usually installed in dusty places such as factories. After a period of time, there is a thick layer of dust on the terminal block, which can easily cause poor contact of the terminals. Cleaning the dust on the terminal block wastes a lot of manpower and material resources, and it is easy to cause the terminal to fall off or the wire to detach during the cleaning process, causing the entire equipment to shut down and unable to operate normally, affecting the normal use of the equipment.

[0003] The Chinese patent application number 201721155837.9 discloses a portable secondary terminal block isolation and protection device, which is provided with a support frame and a telescopic cover body. The support frame is clamped on the secondary terminal block, and a movable slot is provided on the side bracket of the support frame. The telescopic cover body forms a gear rack transmission mechanism through the movable support rod at the end and the movable slot; the telescopic cover body is telescoped on the support frame to isolate and protect the secondary terminal block. The portable secondary terminal block isolation and protection device achieves the function of protecting the wiring terminals by adding a flexible cover curtain to the wiring terminals of the terminal block, but the device still has the following problems:

[0004] 1. Since there are many cables in the electrical equipment, the length of the terminal block is long, and the flexible cover curtain of the device is connected between two connecting support rods. Due to the long length of the terminal block, more connecting support rods are required. Therefore, when opening the flexible cover curtain, not only a lot of effort is required, but also the opening process is more cumbersome.

[0005] 2. When the distance between the two connecting support rods is too close, the flexible cover curtain between them will be in a drooping state, which may easily cause the flexible cover curtain to touch the wiring terminals. At the same time, the support rods at both ends lack fixing devices, which may easily cause the straight rods to move back and forth.

[0006] Therefore, it is necessary to propose a new type of direct terminal block for three-phase smart electricity meters of State Grid to solve the above problems. Utility Model Content

[0030] refer to Figure 3 and Figure 4 The reset roller 108 includes a torsion spring 110 and a sleeve 111. The sleeve 111 is sleeved on the outside of the torsion spring 110. The initial state of the torsion spring 110 is a stressed state. The excess cover cloth 109 is rolled on the outer wall of the sleeve 111 by rotation. When the distance between the two support rods 107 becomes larger, the cover cloth 109 will be pulled out from the outer wall of the sleeve 111. The center end of the torsion spring 110 is fixed on the support rod 107, and the other end of the torsion spring 110 is fixed on the inner wall of the sleeve 111. The outer wall of the sleeve 111 is connected with the cover cloth 109.

[0031] refer to Figure 5 and Figure 6A rack 112 is connected to the inner wall of the sliding groove 103, and tooth surfaces meshing with each other are arranged on the rack 112 and the card block 114. A cavity 113 is provided on the side wall of the first moving block 104 near one end of the rack 112, and a spring 118 in the cavity 113 pushes the card block 114 to press on the rack 112.

The first moving block 104 and the second moving block 105 move in the sliding groove 103 through the rollers.

[0033] Specifically, refer to Figure 3 A sealing strip 119 is connected to the side of the connecting block 106 away from the cover cloth 109. When the connecting block 106 moves to contact the inner wall of the terminal block body 101, the sealing strip 119 enhances the sealing at the connection to prevent dust from entering. The connecting block 106 is connected to the side wall of the terminal block body 101 through the sealing strip 119.

[0034] Specifically, the cover cloth 109 is made of a transparent insulating material. The transparent material can facilitate the user to observe the terminal blocks when the cover cloth 109 is not opened, and the insulating material can increase the insulation capacity of the device.

[0035] In this embodiment, the terminal block body 101 is installed in the equipment device and is used for connecting the cable connector. The sliding frame 102 is arranged at the top of the wiring terminal area of ​​the terminal block body 101 to protect the wiring position, prevent foreign objects from entering, and avoid the user from accidentally touching the wiring terminal. The first moving block 104 and the second moving block 105 move in the sliding groove 103 inside the sliding frame 102, and the cover cloth 109 is driven to unfold during the movement, so as to protect the wiring position. When the connection block 106 at one end is fixed, when the connection block 106 at the other end is pulled, the cover cloth 109 will be pulled by the connection block 106, so that the cover cloth 109 is pulled out from the outer wall of the reset roller 108. When it moves to the corresponding position, the connection block 106 is fixed by the connection between the clamping block 114 and the rack 112.

When the two pressing plates 116 are close to each other, the block 114 is driven to move through the connecting rod 117, so that the block 114 is pulled into the cavity 113, and the spring 118 in the cavity 113 is compressed. At this time, the connection block 106 can be pulled to move by the pressing plate 116, so that part of the terminal block is exposed, and then the two pressing plates 116 are released, and the spring 118 in the cavity 113 is reset and extended, so as to push the block 114 to press on the rack 112, so as to fix the connection block 106, and the terminal block can be maintained at this time;

[0037] The center end of the torsion spring 110 is fixed on the support rod 107, and the other end is on the sleeve 111. Through the rotation of the torsion spring 110, the cover cloth 109 is rolled up on the outer wall of the sleeve 111, so that the cover cloth 109 is stored to prevent the cover cloth 109 from drooping and contacting the wiring terminal. When the distance between the connecting block 106 and the adjacent support rod 107 becomes larger, the connecting block 106 will pull the cover cloth 109. At this time, the cover cloth 109 will be pulled out from the outer wall of the sleeve 111, thereby increasing the overall length of the cover cloth 109. When it is reduced, the torsion spring 110 drives the sleeve 111 to rotate, thereby rolling up the excess cover cloth 109 on the outer wall of the sleeve 111.

[0038] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
